Yesterday was a disaster for me. I run the Ford Spec Car challenge @Watkins Glen Cup. I qualfied into the race at grid #3. Cool. Started well, first corner - kept my position; the whole first lap - kept my position; second lap - after the eses going uphill, two guys had passed me, I have left them nice spot to overtake since I saw they are both faster than me, and then... like a compelte moron, on the approach to chicane, I was so concentrated on the breaking light of the car in front of me that I missed the breaking point and went straight into the other guy's back. He then took away the car in front of me, and all three of us had to head for repairs. I felt like a complete idiot... So embarassed... I apologized both, but I ruined their race already, completely my fault. I ended up last, since I don't like to quit the race even if I had an accident that had cost me 5 minutes in towing and repairs.
Conclusion - don't push too hard when not confident enough, brake earlier if you are very close to someone's back (if no intention of overtaking), play it safe so you get to finish line in one piece... Lesson learned, it's just a shame it had been learned on someone else's loss.
